5.1. FUNCTION OF ADD/REF/OFF (A/R) BUTTON. TESTING THE RANGE.
Function of
ADD/REF/OFF
button (
A/R
in AR437, add/refresh/disable) depends on the base recorder AR40x.
a)
AR40x connected to power supply, the sensor has not yet been added to the measurement list: short pressing
of the button initiates the procedure of obtaining ID index for the sensor (chapter 9).
b)
AR40x connected to power supply, the sensor is present on the measurement list: short pressing of the button
refreshes (updates) the measurement data from the sensor
c)
AR40x not connected to power supply or outside the range: pressing button for about 10s turns off the sensor
(max. after approx. 35 seconds, unused sensors should be turned off to save the battery and eliminate their
impact on the operating system, chapters 9 and 11, sub-p. b).
This button may be used to test the radio range at the target location, but if the sensor is
OFF
, then it will always be
added to AR40x list as a new device, even if it was previously listed. Therefore, after completing the test, you should
rearrange this list or create a new one (using methods described in the operating manual of AR40x i.e. AR407/AR406).
To improve or extend the radio range -
read the operating notes in chapter 12.
6. DESCRIPTION OF THE MEASUREMENT CONNECTOR IN AR433/434
a) numbering of the connector and the method of connecting sensors and measuring signals
b) connection of 2- and 3-wire transducers (
I
out - current,
U
out - output voltage)
7. CONNECTING TO A COMPUTER AND INSTALLATION OF DRIVERS
After you connect the device for the first time, the Windows system (XP/Vista/7/8/10) detects the sensor as "APAR
USB DEVICE" and demands installation of drivers of the virtual COM serial port (MODBUS-RTU protocol, also used
by ARSOFT-CFG-WZ1 software). Use the device manager or the wizard to add new hardware - manually specify
the location that contains the drivers (CD-ROM, DRIVERS directory, or downloaded from www.apar.com). For
Windows 7/10 you can use automatic downloading of the driver software from the Windows Update website.
In Windows 7, you may enter the Device Manager and perform the installation in the following manner:
1. Right-click "
APAR USB DEVICE
" and select "
Update driver software
",
then "
Browse my computer for driver software
"
2. Use button "
Browse…
" to indicate the location (DRIVERS folder) containing the drivers and click "
Next
"
3. Install the virtual COM port "
CDC USB to UART
", press "
Close
"
After the installation is complete, the sensor is shown in the system as a virtual port COMx (x-port number: 1.2 ...).
NOTE
:
In AR437 the USB is available after removing the front cover.
Do not disconnect the sensor from the computer before completing the installation of the drivers.
